Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an engine control method, device, electronic equipment, and vehicle. Background Art

[0002] Hybrid vehicles usually use engines with smaller displacement or power. Especially in hybrid mode, the engine operating point needs to balance the engine noise, vibration and harshness (NVH) performance and fuel economy.

[0003] The related technical solution discloses a method for selecting and switching the operating point of a range extender. The method constructs a working performance optimization function for the range extender, and searches for the target speed and target torque corresponding to the optimal value of the working performance optimization function under the limitation of the target power demand. In this way, the target operating point of the range extender is determined, so as to quickly and accurately match the optimal operating point and working curve of the range extender, thereby achieving the effect of selecting and optimizing the working point of the range extender. The related technical solution also discloses a method for selecting a point for a range extender. The method comprehensively adjusts the torque and speed of the range extender by combining the NVH parameters in the vehicle and the fuel consumption parameters of the range extender to obtain the optimal operating point under the same output power, thereby achieving the selection of the point for the range extender.

[0004] However, currently, NVH performance is usually prioritized at the expense of fuel economy. Summary of the Invention

[0005] This application provides an engine control method, device, electronic device, and vehicle for achieving a balance between vehicle fuel economy and engine NVH performance. The technical solution of this application is as follows:

[0006] According to a first aspect of the present application, a method for controlling an engine is provided, the method comprising: receiving driving information of a vehicle, the driving information including at least one of a window opening, a compressor speed, an audio volume, and an air volume of an air conditioner. Based on the driving information, the vehicle's pedal opening, and / or the battery SOC, the operating mode of the engine is controlled. The operating modes include a fuel economy mode, a table lookup balancing mode, and an NVH priority mode. The fuel efficiency of the fuel economy mode is higher than that of the table lookup balancing mode, and the fuel efficiency of the table lookup balancing mode is higher than that of the NVH priority mode.

[0007] The above-described technical approach controls the engine operating mode based on the vehicle's pedal stroke and / or battery state of charge (SOC), as well as driving information. This allows the engine operating mode to be determined by comprehensively considering driving information, pedal stroke, and / or battery SOC, choosing from fuel economy mode, table-based balancing mode, and NVH priority mode. This allows the matching operating mode to be determined based on the vehicle's operating information, avoiding prioritizing NVH performance and achieving a balance between vehicle fuel economy and NVH performance.

[0008] In one possible approach, controlling the engine operating mode based on driving information, a vehicle's pedal opening, and / or a battery state of charge (SOC) includes determining a current engine operating mode based on the pedal opening and / or the SOC, and switching the engine operating mode based on the driving information and the current operating mode.

[0009] The above technical approach determines the vehicle's engine's current operating mode based on pedal travel and / or SOC. The engine's operating mode is switched based on driving information and the current operating mode. This allows the current operating mode to be adjusted based on the driver's driving behavior, ensuring the engine's operating mode matches the user's driving behavior, avoiding prioritizing NVH performance and achieving a balance between vehicle fuel economy and NVH performance.

[0010] In one possible approach, the driving information includes the window opening, and the engine operating mode is switched according to the driving information and the current operating mode, including: when the current operating mode is the table lookup balancing mode or the NVH priority mode, and the window opening is greater than or equal to the opening threshold, the engine operating mode is switched to the fuel economy mode.

[0011] According to the above technical means, when the window is wide open, the engine operating mode is switched to the fuel economy mode. In this way, when the window is wide open, it is determined that the driver and passengers are tolerating the noise. In this case, the engine operating mode is switched to the fuel economy mode, which can improve fuel efficiency.

[0012] In one possible approach, the driving information includes the volume of the audio system. The engine operating mode is switched based on the driving information and the current operating mode, including: when the current operating mode is the lookup balancing mode or the NVH priority mode, and the volume of the audio system is greater than or equal to a volume threshold, the engine operating mode is switched to the fuel economy mode.

[0013] According to the above technical means, when the audio volume is high, the engine operating mode is switched to the fuel economy mode. In this way, when the audio volume is high, it is determined that the driver and passengers are less sensitive to noise. In this case, the engine operating mode is switched to the fuel economy mode, which can improve fuel efficiency.

[0015] According to the above technical means, when the compressor speed is high, the engine operating mode is switched to the fuel economy mode. In this way, when the compressor speed is high and it is determined that the driver and passengers are less sensitive to noise, the engine operating mode is switched to the fuel economy mode, thereby improving fuel efficiency.

[0016] In one possible method, the driving information includes the air volume of the air conditioner, and the engine operating mode is switched according to the driving information and the current operating mode, including: when the current operating mode is the lookup balancing mode or the NVH priority mode, and the air volume of the air conditioner is greater than or equal to the air volume threshold, the engine operating mode is switched to the fuel economy mode.

[0017] According to the above technical means, when the air conditioning air volume is high, the engine operating mode is switched to the fuel economy mode. In this way, when the air conditioning air volume is high and it is determined that the driver and passengers are less sensitive to noise, the engine operating mode is switched to the fuel economy mode, which can improve fuel efficiency.

[0018] In one possible approach, switching the engine operating mode based on driving information and the current operating mode includes determining the noise sensitivity of vehicle occupants based on the driving information. Noise sensitivity indicates the occupant's sensitivity to sound. Switching the engine operating mode based on the current operating mode and the noise sensitivity.

[0019] According to the above technical means, the noise sensitivity of the driver and passengers is determined based on the driving information, and then the working mode of the engine is adjusted according to the noise sensitivity of the driver and passengers.

[0020] In one possible approach, the engine operating mode is switched based on the current operating mode and noise sensitivity, including: when the current operating mode is a table lookup balancing mode or an NVH priority mode, and the noise sensitivity is less than or equal to a first sensitivity threshold, the engine operating mode is switched to a fuel economy mode.

[0021] According to the above technical means, when the noise sensitivity is less than or equal to the first sensitivity threshold, the engine operating mode is switched to the fuel economy mode. In this way, when the driver and passengers have a high tolerance for noise, switching the engine operating mode to the fuel economy mode can improve fuel efficiency.

[0022] In one possible approach, the engine operating mode is switched based on the current operating mode and noise sensitivity, including: when the current operating mode is the NVH priority mode and the noise sensitivity is greater than the first sensitivity threshold and less than the second sensitivity threshold, the engine operating mode is switched to the table lookup balancing mode.

[0023] According to the above technical measures, when the noise sensitivity is greater than the first sensitivity threshold and less than the second sensitivity threshold, the engine operating mode is switched to the table-based balancing mode. In this way, if the driver and passengers have a moderate level of noise tolerance, switching the engine operating mode to the table-based balancing mode can achieve a balance between fuel efficiency and NVH.

[0024] In one possible approach, the engine operating mode is switched based on the current operating mode and noise sensitivity, including: when the current operating mode is a table-based balancing mode or a fuel economy mode, and the noise sensitivity is greater than or equal to a second sensitivity threshold, the engine operating mode is switched to an NVH priority mode.

[0025] According to the above technical means, when the noise sensitivity is greater than or equal to the second sensitivity threshold, the engine operating mode is switched to the NVH priority mode. In this way, if the driver and passengers are sensitive to noise, the engine operating mode is switched to the NVH priority mode to ensure the comfort of the driver and passengers.

[0026] In one possible approach, driving information includes window opening, compressor speed, audio volume, and air conditioning air volume. Determining the noise sensitivity of vehicle occupants based on the driving information includes determining the noise sensitivity based on the window opening, compressor speed, audio volume, and air volume.

[0027] According to the above technical means, device status information includes window opening, vehicle speed, audio volume, and air conditioning air volume. In this way, the noise sensitivity of the driver and passengers can be determined by multi-dimensional information, thus obtaining a more accurate noise sensitivity.

[0028] In one possible approach, noise sensitivity is determined based on window opening, compressor speed, volume, and air volume. This includes determining the inverse of each of the window opening, compressor speed, volume, and air volume, and weighting the inverse of the window opening, compressor speed, volume, and air volume to obtain a weighted inverse of the window opening, compressor speed, volume, and air volume. The noise sensitivity is determined as the sum of the weighted inverses of the window opening, compressor speed, volume, and air volume.

[0054] In order to enable ordinary people in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0055] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0056] like Figure 1 As shown, an embodiment of the present application provides an engine control system 10, which includes an electronic device 101 and an engine 102. The electronic device 101 is connected to the engine 102.

[0057] In some embodiments, electronic device 101 is configured to receive vehicle driving information, including at least one of window opening, compressor speed, audio volume, and air conditioning airflow. Based on the driving information, the vehicle's pedal opening, and / or the battery SOC, the operating mode of engine 102 is controlled. The operating modes include fuel economy mode, table lookup balancing mode, and NVH priority mode. Fuel economy mode offers higher fuel efficiency than table lookup balancing mode, which in turn offers higher fuel efficiency than NVH priority mode.

[0058] based on Figure 1 ,like Figure 2 As shown, the engine control system 10 provided in this embodiment of the present application further includes: a body controller 103, a battery controller 104, an accelerator pedal 105, a window controller 106, an air conditioning system controller 107, an audio system controller 108, and an engine controller 109. The body controller 103, the battery controller 104, the accelerator pedal 105, the window controller 106, the air conditioning system controller 107, the audio system controller 108, and the engine controller 109 are all connected to the electronic device 101. The engine controller 109 is connected to the engine 102.

[0059] In some embodiments, the vehicle body controller 103 is configured with an electronic stability program (ESP), and the battery controller 104 is configured with a battery management system (BMS). The electronic device 101 may be a vehicle control unit (VCU) or other control device, which is not limited in this embodiment of the present application. The engine controller may be an electronic control unit (ECU).

[0060] The vehicle in the embodiment of the present application may be a hybrid vehicle. In this case, the engine 102 is an engine in a hybrid vehicle. For example, the engine 102 is an engine in a range extender.

[0061] In the embodiment of the present application, the body controller 103 collects the wheel speed signal of the wheel speed sensor through ESP, converts the wheel speed signal into vehicle speed and sends it to the electronic device 101. The battery controller 104 calculates the SOC of the battery in real time or periodically through the BMS, and sends the SOC of the battery to the electronic device 101. The battery controller 104 can also collect battery information such as the current and voltage of the power battery. The window controller 106 sends the window opening to the electronic device 101. The air conditioning system controller 107 sends the status, gear position and air volume information of the air conditioning to the electronic device 101. The audio system controller 108 sends the status and volume of the audio to the electronic device 101. In addition, the electronic device 101 collects the pedal opening of the accelerator pedal 105. In this way, the electronic device 101 obtains the operating information of the vehicle.

[0062] Furthermore, electronic device 101 calculates an engine operating point (including information such as torque and speed) that balances fuel economy and NVH performance based on the vehicle's operating information. Subsequently, electronic device 101 transmits the engine operating point to engine controller 109. In response, engine controller 109 controls the operation of engine 102 based on the engine operating point.

[0063] In another embodiment, the electronic device 101 controls the engine operation according to the engine operating point when determining the engine operating point, so that the engine operates at a speed and torque corresponding to the engine operating point.

[0064] In the embodiment of the present application, the engine operating mode is determined based on the operating point and target correspondence. The target correspondence includes multiple operating points and the operating mode corresponding to each operating point. Different operating points correspond to different fuel efficiency and speed.

[0065] To better understand the configuration of energy storage media, e.g. Figure 3 As shown, an embodiment of the present application provides an engine control method, including: S301-S302.

[0066] S301: Receive vehicle driving information.

[0067] The driving information includes at least one of a window opening, a compressor speed, an audio volume, and an air volume of an air conditioner.

[0068] In some embodiments, the electronic device obtains the vehicle's driving information periodically or in real time.

[0069] In the embodiment of the present application, the driving information may also include other vehicle operating parameters, which are not specifically limited in the embodiment of the present application. For example, the driving information may also include vehicle speed.

[0070] In the embodiment of the present application, the window opening, compressor speed, audio volume, and air conditioning air volume are expressed as percentages, for example, the window opening is 50% or the audio volume is 30%.

[0071] S302: Control the engine operating mode according to driving information, the vehicle's pedal opening and / or the battery SOC.

[0072] The operating modes include fuel economy mode, table lookup balancing mode, and NVH priority mode. Fuel economy mode is more fuel efficient than table lookup balancing mode, and table lookup balancing mode is more fuel efficient than NVH priority mode.

[0073] In some embodiments, the electronic device determines the current operating mode of the vehicle's engine based on the pedal opening and / or the SOC. Based on the driving information and the current operating mode, the engine's operating mode is switched. This step is described in detail in the following embodiments and will not be repeated here.

[0074] In other embodiments, the electronic device determines the engine operating point based on the vehicle's pedal opening and / or battery SOC and driving information, and determines the engine operating mode based on the engine operating point. Further, the electronic device controls the engine to operate according to the determined operating mode.

[0075] For example, if driving information includes window opening, compressor speed, audio volume, and air conditioning air volume, the electronic device determines the engine operating point based on the vehicle's pedal opening, window opening, compressor speed, audio volume, and air conditioning air volume.

[0076] For example, if driving information includes window opening, compressor speed, audio volume, and air conditioning air volume, the electronic device determines the engine operating point based on the vehicle's pedal opening, vehicle speed, window opening, compressor speed, audio volume, and air conditioning air volume.

[0077] In the embodiment of the present application, the fuel economy mode, the lookup table balancing mode and the NVH priority mode are three different operating modes of the engine, which are used to characterize different working states of the engine. In the fuel economy mode, the engine has the highest fuel efficiency, but generates relatively high noise; in the lookup table balancing mode, the engine balances noise and fuel economy; in the NVH priority mode, the noise generated by the engine is relatively low to improve the comfort of the vehicle, but the fuel efficiency is relatively low. The fuel economy mode, the lookup table balancing mode and the NVH priority mode correspond to different operating points of the engine, respectively. In this way, the operating modes of the engine are divided according to the operating points. In actual applications, the fuel economy mode, the lookup table balancing mode and the NVH priority mode can also be named as other modes, and there is no specific limitation on this.

[0078] The engine control method provided in the embodiments of the present application provides at least the following beneficial effects: controlling the engine operating mode based on the vehicle's pedal opening and / or battery state of charge (SOC), as well as driving information. Thus, when determining the engine operating mode, the driving information, pedal opening, and / or battery SOC are comprehensively considered, and the engine operating mode is determined from a fuel economy mode, a table-based balancing mode, and an NVH priority mode. This allows the matching operating mode to be determined based on the vehicle's operating information, avoiding prioritizing NVH performance and achieving a balance between vehicle fuel economy and NVH performance.

[0079] In one design, the above S302 includes: S3021-S3022.

[0080] S3021. Determine the current operating mode of the vehicle's engine based on the pedal opening and / or SOC.

[0081] As one possible implementation, when the vehicle's range extender is activated, the electronic device obtains the battery's SOC and pedal position in real time or periodically. Furthermore, the electronic device determines the vehicle's engine's initial operating point based on the battery's SOC and / or pedal position. For example, the electronic device determines the engine's initial operating point based on the battery's SOC. For example, the electronic device determines the engine's initial operating point based on the pedal position. For another example, the electronic device determines the vehicle's engine's operating point based on the battery's SOC and pedal position, and determines the current operating mode based on the engine's operating point.

[0082] In some embodiments, the electronic device, upon obtaining the battery SOC, determines the engine's fuel efficiency and NVH value based on the battery SOC, and determines the engine's operating point based on the fuel efficiency and NVH value. The engine's operating point may correspond to an initial speed and initial torque, or may correspond to other engine parameters, which are not limited in this embodiment of the present application.

[0083] In some embodiments, the fuel efficiency of the engine may be negatively correlated with the SOC of the battery. Thus, when the vehicle's battery level is low, the fuel economy of the engine is prioritized, improving the fuel efficiency of the engine to replenish the battery.

[0084] S3022: Switch the engine operating mode according to the driving information and the current operating mode.

[0085] As one possible implementation, the electronic device determines the noise sensitivity of the vehicle's occupants based on driving information. Noise sensitivity represents the occupants' sensitivity to sound. Furthermore, the electronic device switches the engine's operating mode based on the current operating mode and noise sensitivity.

[0086] In some embodiments, for example, driving information includes window opening, compressor speed, audio volume, and air conditioning air volume. The electronic device determines noise sensitivity based on the window opening, compressor speed, audio volume, and air volume. For example, the electronic device calculates noise sensitivity based on the window opening, compressor speed, audio volume, and air volume.

[0087] For example, the electronic device separately determines the window opening, compressor speed, volume, and the inverse of the air volume, and weights the inverse of the window opening, compressor speed, volume, and air volume to obtain the weighted inverse of the window opening, compressor speed, volume, and air volume. The sum of the weighted inverse of the window opening, compressor speed, volume, and air volume is determined as the noise sensitivity.

[0088] For example, the electronic device determines the window opening, compressor speed, volume, and inverse of the air volume, respectively, and determines the sum of the inverse of the window opening, the inverse of the compressor speed, the inverse of the volume, and the inverse of the air volume as the noise sensitivity.

[0089] In some embodiments, the driving information includes window opening, audio volume, and air conditioning volume. The electronic device also obtains the vehicle speed and determines the noise sensitivity based on the window opening, speed, audio volume, air conditioning volume, and a sensitivity determination formula.

[0090] For example, the electronic device determines the inverse of the window opening, vehicle speed, volume, and air volume, and weights the inverse of the window opening, vehicle speed, volume, and air volume to obtain the weighted inverse of the speed, window opening, volume, and air volume. Furthermore, the electronic device determines the sum of the weighted inverses of the speed, window opening, volume, and air volume as the noise sensitivity. Thus, a greater noise sensitivity indicates a lower noise tolerance for the driver and passengers.

[0091] Exemplarily, the sensitivity determination formula is shown in the following formula 1.

[0092]

[0093] Among them, SI is noise sensitivity, a, β, γ and δ are weight values, K1 is the window opening, K2 is the volume of the audio, K3 is the air volume, and K4 is the vehicle speed.

[0094] In the embodiment of the present application, there is no specific limitation on the values of a, β, γ and δ, and the operation and maintenance personnel can set them according to the configuration of the vehicle.

[0095] For example, the electronic device may use the sum of window opening, vehicle speed, volume, and air volume as noise sensitivity. Another example is that the electronic device may weight the window opening, vehicle speed, volume, and air volume and determine the weighted sum as the noise sensitivity. In this way, a higher noise sensitivity indicates a higher noise tolerance level for the driver or passenger.

[0096] In some embodiments, when the current operating mode is the table lookup balancing mode or the NVH priority mode and the noise sensitivity is less than or equal to a first sensitivity threshold, the engine operating mode is switched to the fuel economy mode. It will be appreciated that if the noise sensitivity is less than or equal to the first sensitivity threshold, it is determined that the driver and passenger have a high noise tolerance, and the engine operating mode can be switched to the fuel economy mode.

[0097] In some embodiments, when the current operating mode is the NVH priority mode and the noise sensitivity is greater than a first sensitivity threshold and less than a second sensitivity threshold, the engine operating mode is switched to the lookup balancing mode. It will be appreciated that if the noise sensitivity is greater than the first sensitivity threshold and less than the second sensitivity threshold, it is determined that the driver and passenger have a moderate noise tolerance, and the engine operating mode can be switched to the lookup balancing mode.

[0098] In this embodiment of the present application, when the noise sensitivity is greater than a first sensitivity threshold and less than a second sensitivity threshold, a target fuel efficiency and a target NVH value are determined based on the noise sensitivity and a sensitivity mapping relationship, and the operating point corresponding to the target fuel efficiency and NVH value is determined as the engine operating point. The sensitivity mapping relationship includes multiple noise sensitivities and the fuel efficiency and NVH value corresponding to each noise sensitivity.

[0099] In some embodiments, when the current operating mode is the table lookup balancing mode or the fuel economy mode and the noise sensitivity is greater than or equal to a second sensitivity threshold, the engine operating mode is switched to the NVH priority mode. It will be appreciated that if the noise sensitivity is greater than or equal to the second sensitivity threshold, it is determined that the driver and passenger have a poor tolerance for noise, and the engine operating mode may be switched to the NVH priority mode.

[0100] In order to better understand the relationship between noise sensitivity and the engine's operating mode, for example, when the noise sensitivity is less than or equal to the first sensitivity threshold: 0.3 (such as when the window is wide open or the music volume in the car is loud), it indicates that the driver and passengers are in a state that is insensitive to the engine's NVH performance. In this way, the electronic equipment controls the engine to operate in the mode with the highest fuel efficiency (fuel economy mode). When the noise sensitivity is greater than the first sensitivity threshold: 0.3 and less than the second sensitivity threshold: 0.7, it indicates that the driver and passengers are in a range where fuel economy and engine NVH performance need to be balanced. In this way, according to the noise sensitivity, the target fuel efficiency and target NVH value are found from the sensitivity correspondence to obtain the engine's operating point. When the noise sensitivity is greater than or equal to the second sensitivity threshold: 0.7 (such as when driving at low speed, with the windows and audio system closed), it indicates that the driver and passengers are in a state that is sensitive to the engine's NVH performance, and the electronic equipment controls the engine to operate in the mode with the best NVH performance (NVH priority mode).

[0101] It should be noted that this example is intended only to illustrate the relationship between noise sensitivity and the engine operating mode and does not specifically limit the first and second sensitivity thresholds. The first sensitivity threshold can also be 0.35 or other values. The second sensitivity threshold can also be 0.65 or other values.

[0102] As one possible implementation, if the driving information includes window opening, the electronic device determines whether the window opening is greater than or equal to a threshold. If so, and the current operating mode is table-based balancing mode or NVH priority mode, the electronic device switches the engine operating mode to fuel economy mode. Otherwise, the electronic device determines the noise sensitivity of the vehicle's occupants based on the driving information. Furthermore, the electronic device switches the engine operating mode based on the current operating mode and noise sensitivity.

[0103] As one possible implementation, if the driving information includes audio volume, the electronic device determines whether the audio volume is greater than or equal to a volume threshold. If the audio volume is greater than or equal to the volume threshold and the current operating mode is table-based balancing mode or NVH priority mode, the electronic device switches the engine operating mode to fuel economy mode. Otherwise, the electronic device determines the noise sensitivity of the vehicle's occupants based on the driving information. Furthermore, the electronic device switches the engine operating mode based on the current operating mode and noise sensitivity.

[0104] As one possible implementation, if the driving information includes the compressor speed, the electronic device determines whether the compressor speed is greater than or equal to a speed threshold. If the current operating mode is table-based balancing mode or NVH priority mode, and the compressor speed is greater than or equal to the speed threshold, the electronic device switches the engine operating mode to fuel economy mode. Otherwise, the electronic device determines the noise sensitivity of the vehicle's occupants based on the driving information. Furthermore, the electronic device switches the engine operating mode based on the current operating mode and noise sensitivity.

[0105] As one possible implementation, if the driving information includes the air conditioning air volume, the electronic device determines whether the air conditioning air volume is greater than or equal to a threshold air volume. If the current operating mode is table-based balancing mode or NVH priority mode, and the air conditioning air volume is greater than or equal to the threshold air volume, the electronic device switches the engine operating mode to fuel economy mode. Otherwise, the electronic device determines the noise sensitivity of the vehicle's occupants based on the driving information. Furthermore, the electronic device switches the engine operating mode based on the current operating mode and noise sensitivity.

[0106] As one possible implementation, when driving information includes window opening, vehicle speed, sound volume, and air volume, the electronic device determines whether the window opening is greater than or equal to an opening threshold, whether the audio volume is greater than or equal to a volume threshold, whether the compressor speed is greater than or equal to a speed threshold, and whether the air conditioning air volume is greater than or equal to an air volume threshold. Furthermore, if the window opening is less than the opening threshold, the audio volume is less than the volume threshold, the compressor speed is less than the speed threshold, and the air conditioning air volume is less than the air volume threshold, the electronic device determines the noise sensitivity of the vehicle occupants based on the driving information. Furthermore, the electronic device switches the engine operating mode based on the current operating mode and the noise sensitivity.
